No 1028x786 resolution on HP M50 Monitor On Sarge

[Leonard Chatagnier <lenc@ruralcomm.com>]

Only the 800x600 and 640x480 are available while previously 1028x786 was 
functional and I could switch
to it with cntrl ++.  The higher resolution had been available on both 
woody and sarge kernels(stock).
I have ran dpkg --reconfigure and wajig reconfigure xserver-xfree86 and 
always select the 1028x786 max
resolution.  I've tried modprobe r128 and get a message that file not 
found or doesn't exist but it does and
modprobe gives the same message with or without the full path name.  I'm 
somewhat of a newbie having
been with Debian and linux for about 6 months and don't know what else 
to do.  The pertinent section of my
XFConfig-4 file is copied below for referene and would be glad to 
provide any other needed date:

There are no other entries beside the DEBCONF entries.
I'd certainly appreciate any help or guidance given and if one doesn't 
mind, copy my email address as I'm not subscribed.  Otherwise, I'll 
monitor the list on the web even though its harder to reply in the 
correct format.
Thanks for your help,
